Re: Christ in you..
You say "It is true that without the work of Holy Spirit" What does this mean, what required "work" does the HS have to do?
Part of the workings of the Holy Spirit, is conviction of sin. It is by Him that we come to realize that we need salvation. The Baptism of the Holy Spirit was Promised to all that the Lord shall call.
For the prophecy came not in old time by the will of man: but holy men of God spake [as they were] moved by the Holy Ghost. [1Pet 1:21]
"And when they agreed not among themselves, they departed, after that Paul had spoken one word, Well spake the Holy Ghost by Esaias the prophet unto our fathers, Saying, Go unto this people, and say, Hearing ye shall hear, and shall not understand; and seeing ye shall see, and not perceive: For the heart of this people is waxed gross, and their ears are dull of hearing, and their eyes have they closed; lest they should see with [their] eyes, and hear with [their] ears, and understand with [their] heart, and should be converted, and I should heal them. Be it known therefore unto you, that the salvation of God is sent unto the Gentiles, and [that] they will hear it." - [Acts 28:25-28 KJV]
It was by the Baptism of the Holy Spirit that the Jewish Christians understood that salvation was given to the Gentiles. At the time, there was much debate concerning water baptism for them and the Lord settled the matter by baptism Gentiles in his Holy Spirit. During the discussion Peter stood up and declared:
"And as I began to speak, the Holy Ghost fell on them, as on us at the beginning. Then remembered I the word of the Lord, how that he said, John indeed baptized with water; but ye shall be baptized with the Holy Ghost. Forasmuch then as God gave them the like gift as [he did] unto us, who believed on the Lord Jesus Christ; what was I, that I could withstand God? When they heard these things, they held their peace, and glorified God, saying, Then hath God also to the Gentiles granted repentance unto life." - [Acts 11:15-18 KJV]
